ABSTRACT. The morphologically unique genus Gastrocirrhus has been considered a distinct but systematically uncertain euplotid due to the absence of both morphogenetic and molecular information. Based on the small subunit rRNA gene sequence, the phylogenetic position of Gastrocirrhus monilifer Ozaki & Yagui, 1942 was re‐addressed using multiple algorithms (neighbor‐joining, maximum parsimony, least‐squares, and Bayesian inference methods). Results indicate that: (1) all phylogenetic trees using… Expand
Expanding character sampling for the molecular phylogeny of euplotid ciliates (Protozoa, Ciliophora) using three markers, with a focus on the family Uronychiidae.
TLDR
Six genera in Diophrys-like complex and three other euplotid genera are sampled for SSU-rDNA, ITS1-5.8S-ITS2 and LSU-r DNA, and their phylogenies were inferred with unconstrained and constrained analyses. Expand
Reconsideration of systematic relationships within the order Euplotida (Protista, Ciliophora) using new sequences of the gene coding for small-subunit rRNA and testing the use of combined data sets to construct phylogenies of the Diophrys-complex.
TLDR
Results indicated that combined analyses could be used to construct more reliable, less ambiguous phylogenies of complex groups like the order Euplotida, because they provide a greater amount and diversity of information. Expand
Phylogenetic relationships within the genus Aspidisca (Protozoa, Ciliophora, Euplotida) revealed by ITS1-5.8S-ITS2 region sequences
TLDR
The internal transcribed spacer regions (ITS1 and ITS2) and 5.8S rRNA genes were sequenced in six populations of four Aspidisca species and revealed different topologies of inter-species, inter-genera and inter-subclasses. Expand
Phylogenetic position of the freshwater ciliate Euplotes daidaleos within the family of Euplotidae, obtained from small subunit rDNA gene sequence
TLDR
The small subunit of the nuclear ribosomal operon (SSU rDNA) is sequenced and compared with others of 40 taxa of different Euplotes species and six, well-supported clades and two single taxa are determined. Expand
Further Consideration of the Phylogeny of Some “Traditional” Heterotrichs (Protista, Ciliophora) of Uncertain Affinities, Based on New Sequences of the Small Subunit rRNA Gene
ABSTRACT. The systematic relationships and taxonomic positions of the traditional heterotrich genera Condylostentor, Climacostomum, Fabrea, Folliculina, Peritromus, and Condylostoma, as well as theExpand
Phylogenetic Analyses Suggest That Psammomitra (Ciliophora, Urostylida) Should Represent an Urostylid Family, Based On Small Subunit rRNA and Alpha-Tubulin Gene Sequence Information
TLDR
The morphologically unique ciliate Psammomitra has long been considered as a systematically uncertain stichotrich but the improved diagnosis for this family is as follows: Urostylida possessing extremely contractile, elongated body. Expand
Systematic studies on ciliates (Alveolata, Ciliophora) in China: Progress and achievements based on molecular information.
Due to complex morphological and convergent morphogenetic characters, the systematics of ciliates has long been ambiguous. Since 1990, the Laboratory of Protozoology, Ocean University of China, inExpand
Caryotricha minuta (Xu et al., 2008) nov. comb., a unique marine ciliate (Protista, Ciliophora, Spirotrichea), with phylogenetic analysis of the ambiguous genus Caryotricha inferred from the small-subunit rRNA gene sequence.
TLDR
The results strongly support the distinct separation of the Kiitricha-Caryotricha clade, which always branches basal to the Stichotricho-Hypotrichia-Oligotrichio-Choreotrichi assemblage, and confirm the previous hypothesis that the KiItricha -CaryOTricha group represents a taxon at subclass level within the spirotrichs.

A New Genus of Marine Scuticociliate (Protozoa, Ciliophora) from Northern China, with a Brief Note on Its Phylogenetic Position Inferred from Small Subunit Ribosomal DNA Sequence Data
TLDR
Phylogenetic analyses indicate that Wilbertia groups with Eurystomatella sinica forming a branch that diverges at a deep level from all other pleuronematid scuticociliates, which is closely related to the well‐known Cyclidiidae. Expand
Description of the Rare Marine Ciliate, Uronychia multicirrus Song, 1997 (Ciliophora; Euplotida) based on Morphology, Morphogenesis and SS rRNA Gene Sequence
TLDR
A population of the marine euplotid ciliate, Uronychia multicirrus, found in the littoral zone of the Daya Bay, Guangdong, South China, was investigated using live observation and protargol impregnation method to diagnose this species by possessing a long row of ventral cirri, which has never been seen in all other known congeners.

Phylogenetic positions of Aspidisca steini and Euplotes vannus within the order Euplotida (Hypotrichia: Ciliophora) inferred from complete small subunit ribosomal RNA gene sequences
TLDR
The phylogenetic trees further suggest the postulated relationships among families within the order Euplotida that Uronychia and Diophrys, which were usually placed in the family UronYchiidae, branch later and share closer relationship each other than they are to other euplotids. Expand
Phylogenetic position of the marine ciliate, Certesia quadrinucleata (Ciliophora; Hypotrichia; Hypotrichida) inferred from the complete small subunit ribosomal RNA gene sequence.
The complete small subunit rRNA (SSrRNA) gene sequence of the rare marine hypotrich, Certesia quadrinucleata Fabre-Domergue, 1885, was determined, and found to be 1752 nucleotides long. TheExpand
The Order Euplotida (Ciliophora): Taxonomy, with Division of Euplotes into Several Genera
TLDR
A review of variability of ciliation and nuclei among the 14 genera suggests that lines of evolution may have involved both the loss of cirri and nuclear simplification in the order Euplotida. Expand
Phylogenetic positions of Uronychia transfuga and Diophrys appendiculata (Euplotida, Hypotrichia, Ciliophora) within hypotrichous ciliates inferred from the small subunit ribosomal RNA gene sequences
The small subunit rRNA (SSrRNA) genes were sequenced for the hypotrichous ciliates Diophrys appendiculata and Uronychia transfuga . These two genera branch one after the other above Euplotes onExpand
Phylogenetic position of the marine ciliate, Cardiostomatella vermiforme (Kahl, 1928) Corliss, 1960 inferred from the complete SSrRNA gene sequence, with establishment of a new order Loxocephalida n. ord. (Ciliophora, Oligohymenophorea).
TLDR
The present work indicates that Cardiostomatella vermiforme, together with a closely related species, Dexiotrichides pangi, always form a separate assemblage as a sister group to the scuticociliates sensu stricto, and suggests that this group represents a new order, Loxocephalida n. Expand
Phylogenetic relationships within the class Spirotrichea (Ciliophora) inferred from small subunit rRNA gene sequences.
TLDR
The molecular data support the morphological and ontogenetic evidence that the pattern of 18 frontal-ventral-transversal cirri evolved in the stemline of the Oxytrichidae and was modified several times independently. Expand
Phylogenetic Positions of Two Ciliates, Paranophrys magna and Mesanophrys carcini (Ciliophora: Oligohymenophorea), within the Subclass Scuticociliatia Inferred from Complete Small Subunit rRNA Gene Sequences
TLDR
The trees indicate that the order Philasterida is probably a monophyletic group, within which Mesanophrys carcini is allied in a clade with Anophryoides haemophila that branches basally to other four species: Paranophrys magna, Uronema marinum, Pseudocohnlembus marinus and Cohnilembus verminus.

TLDR
The results indicate that the traditional order Euplotida might comprise 3 paraphyletic groups: the eueuplotids, i.e. euplotid genera with a 5-cirral anlagen mode and a subcortical origin of the oral primordium during morphogenesis, gastrocirrhids and discocephalids, the last of which is possibly a convergent lineage.

TLDR
Halteria groups within the stichotrich clade, supporting the argument that the oligotrichs are not monophyletic as currently conceived, and Phacodinium branches after Euplotes at a deep level, confirming the conclusion that others have reached that this genus is related to the hypotrich and stichOTrich spirotrichs.
